dom4j XML declaration in document

I need to remove XML declaration from dom4j document type

I am creating document by

doc = (Document) D开发者_如何学JAVAocumentHelper.parseText(someXMLstringWithoutXMLDeclaration);

String parsed to Document doc by DocumenHelper contains no XML declaration (it comes from XML => XSL => XML transformation) I think that DocumentHelper is adding declaration to a document body ?

Is there any way to remove XML declaration from the body of

doc

---

The simpler solution I choose is

doc.getRootElement().asXML();

I'm not sure where exactly this the declaration is a problem in your code. I had this once when I wanted to write an xml file without declaration (using dom4j).

So if this is your use case: "omit declaration" is what you're looking for. http://dom4j.sourceforge.net/dom4j-1.6.1/apidocs/org/dom4j/io/OutputFormat.html

Google says this can be set as a property as well, not sure what it does though.

You need to interact with the root element instead of the document. For example, using the default, compact OutputFormat mentioned by PhilW:

Document doc = (Document) DocumentHelper.parseText(someXMLstringWithoutXMLDeclaration);    
final Writer writer = new StringWriter();
new XMLWriter(writer).write(doc.getRootElement());
String out = writer.toString();
